With this format, all data captured by the camera is preserved according to TIFF specifications, with ARW files being quite large in general, with no compression in order to preserve quality. The format is supported by POLYVIEW and features on Canon series like Power Shot and EOS. Canon RAW filesĬanon RAW files are a raster file format for Canon brand cameras with the CRW extension. This is why a RAW picture converter can be so useful, as it lets you convert all these different types of RAW files into more universal, convenient formats like JPEG. They can have different extensions, and in order to open each type of RAW file, a program or device needs to be able to support both the file type itself and the specific model of camera that captured the image in question. The RAW files from a Sony camera, for example, aren't the same as RAW files in a Canon camera.
